Zz method pdf download

This page provides information for learning the ZZ method. ZZ is a modern method for speed solving the Rubik's Cube, originally proposed by Zbigniew Zborowski in 2006.^[1] Michal Hordecki's ZZ Page provides a good background and description of the ZZ method for those who aren't already familiar with it.^[2]

Interpretation of the algorithms presented here requires familiarity with standard cube notation.

If you're new to ZZ, the stripped down beginner version shows only the topics required to get you started.

EOLine

This stage orients all edges on the cube () while simultaneously placing the and edges (Line). This reduces the cube to the <L,R,U> group, meaning the rest of the cube can be solved by turning only the L, R and U faces.

EOLine takes an average of ~6.127 moves and a maximum of 9 moves,^[2] but is without doubt the most difficult part of the ZZ method. For this reason, it is often divided into two sub-stages: (1) Edge orientation followed by (2) placement of the line edges. Also known as "EO+Line".

F2L - The First Two Layers

This stage completes the first two layers by building two 1x2x3 blocks on either side of the Line made in the previous stage. Because all edges are now oriented it is possible to complete this stage using just R, U and L moves.
